System Memory Combinations
The motherboard has two, dual inline memory module (DIMM) sockets. Minimum memory size is 16 MB; maximum memory size is 512 MB. The largest DIMM supported at this time is 256 MB unbuffered. The BIOS automatically detects memory type, size, and speed.
The motherboard supports the following memory features:
- 168-pin DIMMs with gold-plated contacts
- 66 or 100 MHz SDRAM
- Non-ECC (64-bit) and ECC (72-bit) memory
- 3.3 V memory only
- Unbuffered Single- or double-sided DIMMs in the following sizes:
| DIMM Size |
Non-ECC Configuration |
ECC Configuration |
| 16 MB |
2M x 64 |
2M x 72 |
| 32 MB |
4M x 64 |
4M x 72 |
| 64 MB |
8M x 64 |
8M x 72 |
| 128 MB |
16M x 64 |
16M x 72 |
| 256 MB |
32M x 64 |
32M x 72 |
Synchronous DRAM (SDRAM) can be installed in one or two sockets. EDO DIMMs are not supported. Memory size and speed can vary between sockets.
Note: Processors with 100 MHz front-side bus should be paired only with 100 MHz SDRAM. Processors with 66 MHz front-side bus can be paired with either 66 MHz or 100 MHz SDRAM.
All memory components and DIMMs used with the Intel® SR440BX Motherboard should comply with the PC SDRAM specifications. These include: the PC SDRAM Specification (memory component specific), the PC Unbuffered DIMM Specification, and the PC Serial Presence Detect Specification.
Note: It is recommended that SPD memory DIMMs be used with the Intel SR440BX Motherboard. However, the BIOS will allow the use of non-SPD DIMM memory. DIMM Vendors - Web Sites

DIMM Vendors - SDRAM ECC DIMMs
Error checking and correcting (ECC) memory detects multiple-bit errors and corrects single-bit errors. When ECC memory is installed, the BIOS supports both ECC and non-ECC mode. ECC mode is enabled in the Setup program. The BIOS automatically detects if ECC memory is installed and provides the Setup option for selecting ECC mode. If any non-ECC memory is installed, the Setup option for ECC configuration does not appear and ECC operation is not available.
The following table describes the effect of using Setup to put each memory type in each supported mode. Whenever ECC mode is selected in Setup, some performance loss occurs.
| Memory Error Detection Mode Established in Setup Program |
| |
EC Disabled |
ECC Enabled |
| Non-ECC DIMM |
No error detection |
N/A |
| ECC DIMM |
No error detection |
Single-bit error correction,
multiple-bit error detection |
The following tables list DIMMs that have been tested. DIMMs that are not listed should also function properly as long as their specifications are compatible with the devices listed below. In general, DIMM devices that are faster than those specified for a given platform will work, although no extra performance will be realized.
